surgical services departments?
race track plan - answer✔involves a series of ORs around a clean central core; the front entrance to each
OR is from the outer corridor, and supplies are retrieved through a rear entrance to the room leading to
the central-core storage and work areas; soiled entrance areas are situated outside this central-core
hotel plan - answer✔the ORs are situated along a central corridor, with separate clean core and soil
work areas; traffic enters and exits the surgery department through a single entrance or a primary
entrance and holding area entrance situated along the same corridor
specialty grouping plan - answer✔ORs are grouped by specialty, each with its own soiled instrument
work area
OR temperature - answer✔between 68-73 degrees
relative humidity (RH) in the OR - answer✔20-60% set by ANSI, no higher than 50%, 30-60% set by
manufacturers
unrestricted areas - answer✔are usually located near the entrance of the OR; offices, dressing rooms,
preoperative holding, postanesthesia care unit (PACU); street clothes are allowed in these areas
preoperative holding - answer✔area where the patient is prepared for surgery; intravenous (IV) line(s)
and invasive monitoring devices are established here; circulator and anesthesia care provider use this
area for preoperative interview and assessment of the patient's status
postanesthesia care unit (PACU) - answer✔recovery area; may be located adjacent to the surgery
department or in the unrestricted area of the department; divided into a series of individual cubicles
laboratory department - answer✔provides the surgical team with perioperative laboratory values used

radiographic monitoring for orthopedic and other cases
pathology department - answer✔specimens are sent to this department for testing, processing, and
diagnosis
semi-restricted areas - answer✔OR attire is required in this area; scrubs and hair covers are mandatory;
storage rooms for nonsterile instruments, equipment, and supplies
decontamination room - answer✔often located above or below the surgical department; an elevator or
dumbwaiter is used to separately transport sterile and contaminated instruments and supplies; contains
equipment for the gross decontamination of instruments
central sterile supply and processing department (CSPD) - answer✔located outside the surgery
department; it is where the final assembly, sterilization, and storage of instruments occurs as well as the
storage of sterile supplies; also responsible for the processing of instruments
restricted areas - answer✔proper OR attire and masks are required in these areas; OR suites, substerile
rooms, and sterile storage rooms
substerile room - answer✔room that each OR or group of ORs is provided with that contains a scrub sink
and an autoclave steam sterilizer for cleaning and immediate use steam sterilization (IUSS) for
instruments; may also contain a blanket and solution warmer unit
environmental services - answer✔ancillary department responsible for cleaning the semi-restricted and
restricted areas of the surgery department
positive air pressure - answer✔All doors into restricted areas must remain closed during an operation to
preserve ___________________ and help prevent air contamination.
standard size of an OR - answer✔400-600 square feet; some trauma rooms may be at least 800 square
feet due to the advanced imaging technology and the need for additional equipment
electrical outlets in the OR - answer✔contain both 110-volt and 220-volt outlets that must be connected
to a monitored electrical system in the surgery department; situated well above the floor
red electrical outlets - answer✔these are connected to the health care facility's backup generator in
case of power outage and should be used for equipment that is vital to the patient's safety, such as the
anesthesia machine
Extension cords - answer✔______________________ should not be used in the OR.
